Visualization Of Neuronal Geometry In Ventral Nerve Cord Ganglia Of Acheta Domesticus, Gordon William Luke

University of the Pacific Theses and Dissertations

The present is an attempt to show the pattern of innervation, or neuronal geometry, of various nerves leading to their respective ganglia (Fig. 1) and to obtain visualization of the finest terminal branches. A description of the cellular arrangement of a segmental ganglion would be of value in better understanding the results obtained when using the axonal iontophoresis method applied to the third through seventh ventral nerve cord ganglia. A segmental ganglion of the thorax or abdomen is usually an oval mass of nerve tissue, continuous with the interganglionic connectives (Fig. A). Two or three principal lateral nerves extend from …
